I installed the CF-400UV in my 100-gallon saltwater tank and it has made a big difference in water clarity. The UV sterilizer helps reduce algae growth and keeps the water clean. The filter is easy to maintain and the media compartments are spacious. I like the included fine and coarse pads as a starting point.

The filter performs well in my 90-gallon freshwater tank. The flow is strong and the UV light helps keep the water clear. I added my own filter media later, and the system is very customizable. Installation was straightforward thanks to the included plumbing.
